THE ROLE OF ANCIENT KARST IN THE FORMATION OF URANIUM DEPOSIT (GORNAYA SHORIYA)
Marmorized limestones of the Upper Proterozoic are widely viewed as host rocks of the Labysh deposit. The formation of uranium ores in carbonate rocks does not correspond to existing сoncepts of the uranium ore process geochemistry. A detailed study of lode ores of the deposit showed that karst cavities were originally filled with limestone fragments of different sizes and finely-dispersed kaolinite. Further, an input of thermal alkaline solutions led to the leaching of earth silicon of metamorphogenic limestone silicates and formation of “silicinate–tar” veins. In fact, the rocks hosting mineralization are morphologically veined sedimentary wellpermeable rocks with geochemical properties approximating to hydrothermally altered rocks of intermediate composition.
